her after the great distinguishing day, Sunday, are too
many to be distinctly thought of together: a division of three preceding
and three following the day of most note would be much more easily used.
But all this comes too late. It may be, nevertheless, that some individuals
may be able to adjust their affairs with advantage by referring Thursday,
Friday, Saturday, to the following Sunday, and Monday, Tuesday, Wednesday,
to the preceding Sunday. But M. Arson's proposal to alter the names of the
days is no more necessary than it is practicable.

CYCLOMETRY.

I am not to enter anything I do not possess. The reader therefore will not
learn from me the feats of many a man-at-arms in these subjects. He must be
content, unless he will bestir himself for himself, not to know how Mr.
Patrick Cody trisects the angle at Mullinavat, or Professor Recalcati
squares the circle at Milan. But this last is to be done by subscription,
at five francs a head: a banker is named who guarantees restitution if the
solution be not perfectly rigorous; the banker himself, I suppose, is the
judge. I have heard of a man of business who settled the circle in this
way: if it can be reduced to a debtor and creditor account, it can
certainly be done; if not, it is not worth doing. Montucla will give the
accounts of the lawsuits which wagers on the problem have produced in
France.

Neither will I enter at length upon the success of the new squarer who
advertises (Nov. 1863) in a country paper that, having read that the
circular ratio was undetermined, "I thought it very strange that so many
great scholars in all ages should have failed in finding the true ratio,
and have been determined to try myself.... I am about to secure the {209}
benefit of the discovery, so until then the public cannot know my new and
true ratio." I have been informed that this trial makes the diameter to the
circumference as 64 to 201, giving [pi] = 3.140625 exactly. The result was
obtained by the discoverer in three weeks after he first heard of the
existence of the difficulty. This quadrator has since published a little
slip, and entered it at Stationers' Hall. He says he has done it by actual
measurement; and I hear from a private source that he uses a disk of 12
inches diameter, which he rolls upon a straight rail. Mr. James Smith did
the same at one time; as did also his partisan at Bordeaux. We have, then,
both 3.125 and 3.140625, by actual measurement. The second re
